The World’s Largest Fractal Triangle

About 40 volunteers got together in the 505 to assemble 4,036 triangles made by children from around the world. They only needed 2,187 to make a seventh-order fractal triangle, which would be 96 feet per side. But there were so many submissions, they just kept building.

Next year, they’ll push it even further with an eighth-order fractal triangle, which is a whopping 196 feet per side and needs 6,561 triangles.
